Digital Carnet turns your paper credit book into an app. Record what each customer owes, snap a photo of the receipt, and send a friendly reminder on WhatsApp — in one tap.
No accounting knowledge. No training. If you can send a WhatsApp, you can use Digital Carnet.
Just a name and a phone number. That's the whole setup — add a customer in seconds the first time they buy on credit.
Tap the amount, choose credit or payment, and snap a photo of the receipt or paper slip if you have one. Done.
One tap sends the customer a clear message with their new balance — and their last 5 transactions — straight to WhatsApp.
Digital Carnet keeps every customer, every sale, every payment in one place, and does the chasing you never have time for.
The hardest part of credit is asking for your money back. Digital Carnet writes the message for you — polite, clear, with the balance and the last 5 transactions — and sends it on WhatsApp in one tap.
A big, simple keypad. Tap the amount, choose whether they paid you or took goods on credit, and attach a photo of the invoice or paper slip so you always have proof.
Swipe between reports: your late payers, customers who've never paid, and a monthly summary of credit given versus cash received. From any report, send a reminder straight to WhatsApp.
Swipe through the app — every screen is one clear job.

Never paidDigital Carnet backs up everything — including the photos — to a private folder in your own Google Drive. We never keep a copy. Get a new phone, sign in with the same Google account, and every customer, balance and receipt comes straight back.
Data and receipt photos live in a private folder in your Drive — not shared, not sold, not readable by us.
Phone lost, stolen or broken? Sign in on a new one and your entire credit book is restored automatically.
No more torn pages or a diary left at home. Your records are always in your pocket and always current.
You're not left alone with a download. It's set up with you, supported, and shaped around how your business actually works.
Use the full app free for a month — nothing held back. Keep it if it earns its place; it's just Rs 250 / month after that.
Need a change or a new feature for the way you work? Tell us — we build it. We'll always agree any change with you first, so you know what's involved before we start.
Something not working right? We're here. Ongoing support is part of your subscription — a problem with the app is ours to fix.

No. Only you use the app. Your customers just receive a normal WhatsApp message with their balance and recent transactions — nothing to install on their side.
